i Honestly love the idea of a new bst 2hr that calls extra mobs for a brief period.maybe they'd stay grouped with your current pet and only assist it, not being controllable by the player.they'd stick around for the duration of the 2hr then at it's end, use their best ready moves [if in combat] then leave. As the idea above me suggested.
that, or i'd even be ok with like, consuming your pet to call a smaller version of a HNM to assist you for it's duration.
anything that kills my pet just for buffs? not worth my pet.i do pay for these pets you know.
